To all whom it may concern.'

Be it known that we, ARNOLD Conn and LOUIS M. KRONIIEIMER, citizens of the United States, residing at New York city, Manhattan borough, county and State of New York, have invented certain new and useful lmprovements in Loose-llrap-Gluing Machin es, of which the following is a clear, full, and eX- act description.

This invention relates to a device adapted. to apply glue or paste to loose-wraps, the said loose-wraps being used in the manufacture of paper boxes. As the use of loosewraps in the manufacture of paper boxes is well known, a detailed description of such usage will be omitted.

We will now proceed to describe our invention, the features of which we will iinally claim, reference being had to the accompanying drawing wherein:

Figure 1 is a side elevation of a glue applying machine embodying our improvements; Fig. 2 is a plan view thereof; Fig. 3 is a section taken on a line a-a in Fig. 1; Fig. 4 is an enlarged detailed view, showing one of the glue applying elements partly in section; a portion of the operating lever therefor and slide rest being shown; and Fig. 5 is an enlarged sectional plan view, taken through the sleeve which carries the table operating shaft, the section being taken on a line b-b in Fig. 3.

Referring to the drawings particularly to Fig. 1, the immoral 1 indicates a supporting frame, upon which the elements of the machine are placed. The top of the frame 1 is provided with a plate 2, and from each corner of the plate 2 extend columns 3. The columns 3 support slide-rests 4, the said sliderests being adapted te slid ably support a carrier or slide 5. Upon the slide 5, we place glue applying elements 6 and 7, the said glue applying elements being adapted for adjustment longitudinally of the carrier 5. The elements 6 are provided with set screws 8, which hold them in an adjusted position. The elements 7 are held in position by means of collars 9, the said collars being provided with set screws 10 (see Fig. 2). The glue applying elements 6 are composed of a frame 11, provided in the lower end thereof with a jaw 12, the said jaws 12 are adapted to retain 'rollers 13, the said rollers 13 being retained in position by studs 14. The glue applying elements 7 are composed of a frame 15, the lower end of which is provided with a jaw 16 adapted to retain, by means of a stud 17, a roller 18. The frame 15 is adapted for movement transversely of the carrier 5. To adapt the frame 15 for the said transverse movement, the upper end of the said frame is provided with a jaw 19, which is adapted to fit over the carrier 5. Over the jaw 19 We place a cap 20, which is adapted to take the thrust of the spring 21, which is interposed between the said cap 20 and carrier 5 (see Fig. 4). Beneath the carrier 5, the frame 15 is provided with a slot 22, (see Fig. 3), in which a wedge 23 is adapted to slide; the wedge 23 controls the transverse movement of the frame 15. To actuate the wedge 23, we place adjacent one end of the slides 4, a cross-bar 24, against which the wedge 23 will strike when the carrier 5 is nearing the end of its backward stroke. Adjacent the front ends of the slides 4, We place a cross-bar 25, against which the front end of the wedge 23 will strike when the carrier 5 is nearing the end of its forward stroke.

The movement of the carrier 5 is reciprocating and slides back and forth on the slides 4 during the operation of applying glue or aste to the material 26, on the, or retained l y, the table 27, the ends of the carrier 5 are provided with slides 28, the said slides being adapted to engage the slide rests 4, as shown in Fig. 3.

To reciprocate the carrier 5, we in this instance employ a bell-crank lever 28,which is pivoted to the frame 1 as at 29. The upper end of the lever 28 is provided with a slot 30, through which a pin 31, which connects the carrier 5 and slide 28, is adapted to pass. The arm 32 of the lever 28 is connected to a crank-arm 33 by a link 34. As can be seen in Fig. 3 there is a lever 28 on each side of the frame 1; there being also a crank-arm 33 on each side of the frame 1, as well as two links 34. The crank-arms 33 are attached to, and operated by a driving shaft 35, the said driving shaft having loosely mounted thereupon a driving pulley 36. The pulley 36 1s rovided with a clutch member 37, whic is adapted to engage the clutch member 38, which is keyed to and rotated by the shaft 35, the clutch 38 is slidably mounted upon the said key, which is indicated by 39. The clutch 38 is operated to engage, or to be caused to disengage the clutch member 37,

by means of a bell crank lever 40, which is 110 operated by a treadle-lever 41. `When the outer end of the lever 41 is pressed downwardly, the clutch 38 will engage the clutchmember 37, whereby the shaft 35 is caused to rotate, it being oi' course understood that the pulley 36 will be in motion. rlhe shalt 35 will continue to rotate as long as the outer end oi' the lever 41 is held in a depressed position. `When the i'oot is taken oil the en d oi' the lever 41 the reaction ol' the springs 42 and 43 will cause the clutch 38 to leave the clutch member 37, whereby the sha'lt 35 will cease to rotate.

For the purpose ol keeping the periph eral surface ol' the rollers 13 and 18 covered with glue or paste, we provide a pasting roll 44, which is adapted to rotate in a trough 45, the said trough containing paste or glue. The roll 44 is constantly rotated by a belt wheel 46 (see Fig. 1). 1N ieu the carrier 5 is at its extreme rear position, the rollers 13 and 18 will contact the roll 44, whereby the said rolls will be supplied with glue or paste l'or the next operation.

One ol'l the chiel objects ol this invention is to apply glue or paste in the l'orm ol lines, or paths to the surlace el' the material, at dil'- l'erent angles. 1n this instance, the table 27 is illustrated as being rectangular in shape; the material 26 being ol' the same shape. As the carrier 5 travels l'orward the glue applying rolls, or elements, 18 will contact the top surface 0l' the material 26, and apply the glue in the l'orm oi paths, or lines, as indicated by the dot and dash lines 47, in Fig. 2. When the carrier 5 leaves the table 47, near the end ol the forward stroke, the table 27 will be turned or partially rotated, by a mechanism to be hereinafter described, and caused to assume a position at aright angle to the position oi' the said table during the 'forward movement of the carrier 5. As has been stated during the forward movement oll the carrier 5, the rolls 18 have contacted the material 26. When the carrier 5 has reached the end o'll the said l'orward stroke, the wedges 23 will have struck the crossbar 2 5, whereby the said wedges have been forced rearwardly, thereby permitting the spring 21 to raise the -l'rames 15 and carry the rolls 18 upwardly. During the operation above described, the table 27 will have been shil ted or partially rotated to the hereinbel'ore mentioned position, namely; at a right angle to the position previously held by the said table. The position to which the table 27 will be shil'ted is indicated by the dotted lines 43 in Fig. 2. When the carrier 5 returns, on its backward stroke, the rolls 13, in the frames 11, will contact the material 26, and make a line or path composed oi' glue, as indicated by the dot and dash lines 49 in Fig. 2. During the backward stroke of the carrier 5, the rolls 18 will not touch the material 26, l'or the reason, that the said rolls have been raised by the springs 19, as hereinbeiore described. After the carrier 5 leaves the material 46, the table 27 will be again shifted, or partially rotated to assume its lormer position, as shown by lull lines in Fig. 2. Just bel'ore the completion el the backward stroke el' the carrier 5, the wedges 23 will strike the cross-bar 24, and be pushed l'orward, whereby the 'frames 15 will be forced downwardly, thereby lorcing the rolls 18 to a position l'or contacting the material 26, upon the next lorward stroke oil the carrier.

lt is obvious from the foregoing descrip tion that the glue applying elements, together with the movement oi the table are adapted to apply glue or paste to the surface of the material in paths or lines at an angle to each other, in this instance, at right angles.

No will new proceed to describe the operation oll shifting or intermittently rotating the table 27. The i'rame 1 is provided with a cross-bar 50, which is adapted to rotatably support asleeve 51. Within. the sleeve 51, we place a shaft 52, the said shalt being keyed to the sleeve 51, by means of a key 53. The shai't 51 is rotated by the sleeve 53, the said shaft being also adapted for movement longitudinally of the sleeve 51. Adjacent the lower end of the sleeve 51, we place a plurality el studs 54, the said studs being carried by a hub 55, which in turn is rigidly secured to the sleeve 51. To the shaft 35, we secure a hub 56, the said hub being provided with arms 57 and 58. The arms 57 and 58 are long enough to strike the studs 54, when the shaft 35 is rotated. By referring to Fig. 1 it will be seen that the arms 57 and 58 are slightly in advance of a right angular position, with respect to the crank arms 33. 1t will be also seen by referring to Fig. 2, that the studs 54 are out of alin'ement with a line drawn centrally oli the length of the table 27. r1he reason lor placing the arms 57 and 58 in advance ol the crank-arms 33, and for placing the studs 54 out of alinement with respect to the table 27, is to cause the arms 57 and 58 to contact with studs 55 before the carrier 5 has reached the limit oi its stroke, for example, and referring to Fig. 1, supposing the machine to be started, revolving in the direction of the arrow A, the arm 58 will travel upwardly, at the same time that the carrier 5 would be traveling forwardly, or in the direction of the arrow B. Owing to the advanced position oi the arm 58 with respect to the crank-arm 33, the said arm 58 will strike the arm 54 and carry it around. The said arms will be so positioned as to cause the contact thereof at about the time that the rolls 18 lclear the material 26, and during the remaining partei the revolution of the crank-arm 33, that is to say, until it comes to the next dead center, the sleeve 51, shaft 52 and table 27 will be given a quarter turn,

a similar action will occur when the carrier 5 approaches the end of its next or, backward, stroke. Y

This machine is especially designed to ap- Ely glue or paste to loose-Wraps for paper oXes, but it is obvious that any material other than paper may be thus treated. p

The table 27 is herein illustrated as retaining a pile of material composed of separate sheets, as the to sheet is treated, it is taken orf, thereby subjecting the neXt sheet to treatment. 1t is quite obvious that when a sheet is taken oli the top of the pile, that the table 27 should be fed upwardly, to attain this end, we place in the lower end of' the sleeve 51 a bushing 59, which is keyed to the sleeve 51, as shown in Fig. 5, and is adapted for vertical movement therein. The top of the bushing 59, contacts the lower end of' the shaft 52 as can be seen in Fig. 3. The bushing 59 is threaded and is adapted to engage the threads ot a spindle 60, the said spindle being actuated by agear 61; the gear 61 rests upon a shoulder 62, on the shaft 35. To actuate the gear 61, we mount upon the shaft 35, an interrupted gear 63, the said gear having teeth 64, throughout a portion only of its circumference. Once in every revolution ofthe shaft 35, the teeth 64 ofthe gear 63 will mesh with the teeth of the gear 61, and rotate the said gear 6]., a certain amount. When the gear 61 is rotated, the spindle 60, which is carried thereby is likewise rotated, whereby the bushing 59 is carried upwardly, which in turn, forces the shaft 52, and table 27 carried thereby, upwardly. The amount of the upward feed of the table 27 will be sufficient to compensate for the extracted sheet of material.

To prevent the table 27 from racing while being rotated, we provide a disk 65, which is attached to the sleeve 51, and a spring 66, which is adapted to exert sufficient pressure, upon the disk 65 to prevent the sleeve 51. from racing. To cause the table 27 to stop in the proper position, we provide the disk 65 with notches 67, the said notches being adapted to receive the end of' a spring 68. When the table is rotated to change its position, the end of the spring 68 will jump into a notch 67, and thereby stop the table at a proper point. When the teeth of the gear 63 are not in contact with the piece of the gear 61, the said gear 61, spindle 60 and bushing 59 will revolve with the sleeve 51. This action will not act to detriment of the feeding mechanism.
